is 350 non-refundable, unless the whole thing falls through. If you change your mind then i guess you are S>O>L. Then I believe it is 125+lodging for Greg and Seb. I apologize in advance if the 125+lodging is wrong, im sure My Harley will chime in. But the 350 deposit is correct. The more we get the cheaper it will be. Some come on and get a great tune and im sure some extra wisdom on your Z. that part is priceless.
